Help for GLLPSF

PURPOSE
GLLPSF generates a two dimensional point spread function in fft format
suitable to be converted into a two dimensional optical transfer function
by vicar program fft22. The output of fft22 can be input to vicar program
wiener as the second input file.

EXECUTION
    gllpsf out=a.img nl=1024 ns=1024

OUTPUT FILES:
The output is a real image nl by ns in fft suitable format, ie: with the
origin of the psf at the upper left.

EXAMPLE
  gllpsf out=psf nl=512 ns=512 psf=(1.,0.,0.,10.)
  fft22  inp=psf out=otf 
  fft22  inp=pix out=fftpix nl=512 ns=512
  wiener inp=(fftpix,otf) out=fixfftpix sn=45.
  fft22 inp=fixfftpix out=newpix mode=inverse format=half
